of which the following is aspecification."

This invention relates to "machines for working on cans, particularlyjniachines for seaming heads or ends on cans orcan-bodies,

and aims to provide improvements therein.

The presentf invention provides a canworking or seaming machine in whichthe general construction is much simplified The invention also providesa simplified and improved means for feeding the can-heads or ends; a"simplified and improved means.

i for ejecting the cans ifron a seaming or trated in other workingposition; and a simplified and improved means for properly positioningthe cans orbodies in the seaming or other working position. Certainfeatures of the invention are applic'ableto other types of metal workingmachines. I

Other features of improvement will be hereinafter pointedout.

the lower part of the ma view a on the the table being adjustable bymeans of the threaded shaft 9? with hand-wheel.

The table G has mounted therein the pad or plunger H5 which acts to liftthe cans into the position wherev they are acted upon" by the seamingrolls. The pad His lifted by a sliding block it having a rolle'r'hwhich, fits Within a cam groove 7L2 inv a block 7:. keyed upon the shaft0. v Means are preferably provided for prop erly locating or positioningthe can bodies under-the seaming ens. This means preferably comprisesaguide, or a pair ofqguides I, preferably attached tothe pad Hyandafinger or fingers J adapted to push the canbodies upon the pad H betweenthe guides. The guides z are-adapted to position the can-bodiessymmetrically with respect to a plane passing through the axis'of'thescan ing head. The guides'I are preferably pro vided with undercut, andslightlycon-verg ing ribs 2', the ribs being so spacedfroin'one anotherthat they oppose with slight I fric-.

tion the movement of the can-bodiesY-between them. The finger-orfingersfll are preferably mounted upon a rotating. disk 7" whichis-ca'r'ried by a shaft y' suitably driven from the vertical shaft Cthrough'a chain .7 and sprockets 9' The shaft. y' is preferably made intwo parts and connected I bya Slip connection 7' T he slip connection}is of importance, andpermitsthe sprockets and the lower part of theshaftfto continue to rotate when a jam occurs which prevents the" actionof; or places an "undue strain upon, thefingers J. j

Asuitableineans L may,be provided for feeding the cans into'position to'be acted upon by the fingers J This means may coniprise a table Z havinga slid-sway Z thereon,

and an endless chain Z having-fingers Z adapted to push the cans "alongthe slide way. The chain Z maybe driven by sprocket Z upon the shaft: j"The table Z preferably has an adjustable guidestrip Z? strip Zmayalsobe pro thereon; A I guide vided.

The fingers J are preferably adjustable,

asby: means. of slots therein through which the fastening bolts pass,"wherebytlie extent to which the can-body is pushed between the guidesonthe pad H may be nicely. adjusted:

The machine may'also comprise the imf. proved meansM for feedingcan-heads or m is provided with an arcuate'opening m therein, the lengthof the are being somewhat ends on to the can-bodies. This meanspreferably comprises a table m having a suitable magazine or hopper mthereon for holdlng a stack of can-heads orends, and a slide m The slidem may bereciprocated by means of the rod m the lever m and the link m,the rod m receiving motion from a crank disk m, which latter may besuitably driven from the vertical shaft C through sprockets m m and achain m The slide greater than a semi-circle. The diameter of theopening is slightlyless than that of the can-heads or ends,and the-edgeof the slide adjacent the opening is grooveth so as to provide :a ledgem upon which the edges of the can-heads or ends are adapted'to restj Thedistance betweenthe inflected or incurved ends of the opening issuchthatv a can-body may pass between the same, and t the portions m mof the slidexat theinfiected ends of the opening are such as to vprevent a can-head-orend which. is resting upon the ledge m, frompassing horizontally ofl ofthe slide; The ledge m is preff erably formedin a separate piece of metal m set'into the slide 9213, the part m beingcapable ofsubstitution, whereby other inset portions may, be substitutedto provide for the use of different sized can-headsor ends inthemachine. a The .-throwofthe slide m is such that the centerof theopening, ,at one limit of the reciprocation,-will' be under the centerof L s the stack of can-heads inthe magazine m and at the other limit ofits reciprocation,

under the axisof the seaming head.

As.show-n in Fig, l -the lever ,m is re-. siliently connected to thepivoted linkim by means of a rod m and spring m Thisconstruction-permits of a movement of the leverm after the slide mrhasbeen stopped,

astop-m being provided for stopping the slide slightly before the end ofan oscillationrof the lever m thereby providing a dwell of the slidebeneath the magazine-m I The stop m" is preferably-adjustable upon anarmm thereby permitting of nicely adjusting 1 the stopping of the slidebeneath-the magazine. The dwell of the slide beneath A the "magazinefacilitates the proper reception of=thle lowermost can-head or end uponthe ledge m of the slide. L i

In order to minimize damage owing to a jam inithe can-head feedingmechanism,

the rod 'm is preferablymade 'intwo parts; and the ends connected by asleeve m the 'connectionat'one of the ends being a shear pin m .whichis' adapted to shear when there is unduexstrain upon the rod m -Thetablem -islpreferably supported by rods m fittingin sockets in brackets mattached to the column A. Wingnutsvm serve to fasten the rods an? in thesockets.

The can-head feeding mechanism Mmay be quickly and conveniently detachedfrom the 'machine by loosening the nuts 917/ and disconnecting the rodsm This permits of readily clearing the front of the machine,

where the mechanism M is located in the front of the machine.

The machine preferably comprises means N forejecting the cans from theposition be neath the seaming rolls, after the heads or ends have beenseamed on the can bodies.

This means preferably comprises a collar 22, fitting upon an eccentricnkeyed upon thevertical shaft C. The collar a. has a slotted tailrt whichfits over a pin a on a bracket n? attached'to a fixed part of themachine.

The collar 'n has a pivoted finger n thereon,

the finger n beingfacted upon by a spring a attachedat one end to apinon thefinger, and at the other end toa stud at on the collar n.Theffinger of has a stop n which by; coming into "contact with thecollar n limits the movement of the finger under the V pull'of thespring. Another stop a may be provided on finger n for preventing (bycoming into contact with the vcollar 0%) movementof the finger acrossits dead center with relation to the spring," The action of theeccentric upon the collar a is to give the finger Wan approximatelyelliptical orbital movement. The pathof movement of the finger n issuchthat the finger n moves to a position at the side of acan,

the further movement of the finger pushing the can body from between theguides I (and from beneath. the seaming rolls) onto the deflecting plateP (or other suitable means for carrying coffthe cans) down which thecans shde ofi the machine. The finger n then moves rearwardly out of theway of a can body which may be being Operation: The cans or bodiesbrought to the machine by the feeding means .L are pushed onto'the pad'H by the fingers J. The guides I exert a slight pressure upon the sidesofthe can: and; guide the can to apposition symmetrical to one planepassing throughtheraxisaof the iseaming head. The length of the arms .JI is such that the'can bodies "are pushed toa position on the padsymmetrical withrespect to a plane passing through the-axis .oftheseaming head at right angles to the first plane. The can body is thensymmetrical with relation to the axis'of the seaming head. In case of ajam occurring in the path of the fingers J, the slip connectionf'permits the feed fingers to remain immobile while the drivingconnections continue to run. v a

While the can bodies are being moved on to thepad acan-head ;or end isbeing moved from the bottom; of the magazine to ,a' 7 position under thevseaming head, over the The width of the opening m in the slide m issuch that the slide may move away from the can body, Without binding, asthe slide is moved rearwardly to take up another can-head from themagazine. I After the head is seamed on the can body, the pad II,

and the can thereon, drop, the can is engaged I by the finger of and ispushed on to the plate P, from whence it passes from the machine. Incase a can body; 1s not on the pad II when the slide m moves forward,

can-head being retained upon the slide by the inturned' or inflectedportions m of the slide. In moving rearWardly, the slidem is stoppedinpositionbeneath the magazine by the stop m", and dwells, a moment (thespring M of the link m yielding), and the lowermosthead or end in thestack drops into the "slide, resting upon the ledge m On theforwardmovement ofthe slide 911?, the head or end resting upon the ledgem is slid from beneath the stack, the stack in the meantime beingsupported by the upper face of the slide "in". In case of a jam in thecan-head feeding mechanism, the shear spin m breaks and allowsthe crankdisk m to move independently of the other parts of the can-head feedingmechanism. 7

After the can-head or end has been seamed and around into position toengage and push another, can from the pad. In the case ofa jam of a canuponthe path-the spring a allows thelinger n to yield, thus preventingthe jam from interfering with the motion of the collar n and eccentric nThe inventive ideas tmay receive other mechanicalexpressions than thoseherein specifically illustrated and described.
